  1. Values are presented as n (%) or mean ± standard deviation. *If the respondent selected option #1 on Q8, the scores on Q9 and Q10 should be zero. Similarly, if the respondent selected option #1 on Q13, the scores on Q14 and Q15 should be zero. CRF cardiorespiratory fitness, m-WLAQ modified Worker’s Living Activity-time Questionnaire.
